Periodontics
Answer: 1
Crater-like gingival deformities are seen in ANUG.
Contraindication for distal wedge removal for periodontal surgery in mandibular molar area is
1. Distal root flutings
2. Presence of deep pockets
3. Insufficient space between distal molar & ascending ramus
4. A soft retromolar pad
Periodontics
Answer: 3
A contraindication for distal wedge removal for periodontal surgery in the mandibular molar area is insufficient space between the distal molar and ascending ramus.
Ideal thickness of graft should be
1. 1.0 to 1.5 mm
2. 0.25 to 0.5 mm
3. 0.5 to 1 mm
4. 2-3 mm
Periodontics
Answer: 1
The ideal thickness for a graft is typically between 1.0 to 1.5 mm to ensure adequate healing and integration.
Gingival curettage is the treatment of choice for
1. globulomaxillary cyst
2. bleeding gingiva
3. inflamed swollen gingiva
4. fibrous gingiva
Periodontics
Answer: 3
Gingival curettage is a procedure used to remove inflamed and diseased tissue from the gingiva. It is particularly effective for treating inflamed swollen gingiva, as it helps to reduce inflammation and promote healing.
Which of the following serves to increase the width of attached gingiva on tooth with isolated gingival recession
1) Laterally positioned pedicle graft
2) Free gingival graft
3) Apically displaced flap
4) All of the above
Periodontics
Answer: 1
Increasing the width of attached gingiva is important for periodontal
health and aesthetics. Here’s how these techniques generally perform:
Laterally positioned pedicle graft involves using
tissue from an adjacent site to augment the width of attached gingiva at
the recession site without losing blood supply, making it quite
effective.
Free gingival graft can also increase attached
gingiva, but since it comes from a donor site, the healing and
appearance may not be optimal compared to pedicle grafts.
Apically displaced flap primarily repositions
existing tissue and may not necessarily increase the width of attached
gingiva.
While options 2 and 3 can contribute to increased connective tissue, they
don't specifically target the enhancement of attached gingival width as
effectively as a laterally positioned pedicle graft.
The periodontal fiber group which inserts into two adjacent teeth is the
1. transseptal group
2. circular group
3. horizontal group
4. oblique group
Periodontics
Answer: 1
The transseptal fibers are a type of periodontal ligament fiber that run between the cementum of adjacent teeth. They help maintain the interproximal relationship between teeth and provide support to the gingival tissue. These fibers are important for the stability of the dental arch and help resist the forces that may cause teeth to drift apart.
Circular group fibers encircle the tooth.
Horizontal group fibers run horizontally between the
tooth and the alveolar bone.
Oblique group fibers run from the cementum to the bone
at an angle, providing resistance to vertical forces.
Sensitivity of roots after periodontal surgery results from all of the following except
1) Exposed dentine tubules
2) Exposed cementum
3) Formation of plaque
4) None of the above
Periodontics
Answer: 2
After periodontal surgery, root sensitivity is primarily due to the exposure of dentin tubules (option 1). When the root surface is exposed, the dentin becomes sensitive to stimuli because the tubules can transmit sensations to the pulp.
Exposed cementum (option 2) is less likely to cause sensitivity because cementum is not as innervated as dentin. Formation of plaque (option 3) can lead to sensitivity as it may irritate the surrounding tissues and contribute to inflammation.
A Gracey curette is said to be correctly adapted when the
1. Handle is parallel to the long axis of the tooth
2. Angle of blade to the tooth is 40
3. Lower shank is parallel with the tooth surface being sealed
4. None of the above
Periodontics
Answer: 3
A Gracey curette is correctly adapted when the lower shank is parallel with the tooth surface being scaled.
